MBA: 13" 4 GB 256 GB SSD MBP: 13" 8 GB 320 GB I am heading overseas for the next 12-14 months so ultimate portability and durability are essential! Hence less is more! Here are some of the main criteria for my decision: -I will be using it for my main computer for the next 14 months or so. -SSD being more durable??? - I will be using it for internet, email and simple computing. Nothing heavy duty. Thanks for any insight!
